Just read
Old Man's War by John Scalzi. I enjoyed it, some interesting concepts, but it clearly owes credit to Heinlein (mentioned in the acknowledgements) and Haldeman for some inspiration. My biggest peeve with the book was the way-too-witty dialogue. Reminded me of the nausea-inducing dialogue that Orson Scott Card has been writing for the last ten years. Good book otherwise, and looking forward to the sequels.
Now reading
Frankenstein, and discovering how much license the film industry has taken with the story.
